Can you send units to showdowns one by one instead of all at once to abuse Mask of Foresight?

Ruling: Yes, you can send units to showdowns one by one instead of all at once.

Sequence:

• Each individual unit fights alone against all opponent units
• All damage heals after each combat
• Mask of Foresight triggers between each separate showdown

Nuances:

• This strategy only makes sense if each individual unit can kill at least one enemy unit
• It's beneficial when there's very limited leftover damage each time, making the +1 increase from Mask worth losing the leftover damage
• The strategy can also be valuable with other cards like Imperial Decree
